IMPROVBD STARGH- SlllARll'I'OllI TO ALL WHOM IT MAY CONGERN.

Be it known that I, Consumi GILBERT, of Bualo, in the county of Erie, and State of New York, have invented new and useful Improvements in Starch-Separators; and T do hereby declare that the following is a i full, clear, and exact description thereof, which will enablev those skilled in the art to make and use the same.

reference being had tothe accompanying drawings, forming part of this specification, in which Figure 1 is a sectional side elevation of my invention, the section being taken through the line 1': :z: of iig. l, which latter is a top or plan view of the same.

'Similar letters of reference indicate corresponding parts. i v The object of this inventioaisto improve a machine used in the manufacture of starch,`whiciimachinc is usually called a separator, and its otlice is to separate, by moans of a bolting-cloth, forming part of it, the coax-ser particles ot' the stock from the'fineramylaceousparticles, whichare afterward'mampulatedto form starch.

The separators, as previously made, consist of a rectangular frame of wood, having for u b'ottoma bolting cloth of muslin or other nc-mcshed fabric. This frame is agitated with a longitudinalreciprocating movement from apitman and crank-pulley, or similar device. f

The finer particles of the stock pass through the bolting-cloth, and are received in an linclined box or receiver, over which the bolting-frame is arranged;

The coarser particles of stock pass o from the lower end of thebolting-frume. My invention contains these general features, and is lmore particularly designed as an-improvemcnt ou a separator used by J. J., Gilbert (see patent No. 65,664) in a. patent for improvement in thc manufacture of starch. l Y, The improvements consist in the method of supporting and vibrating the bolting-fram e, and also tho'method of supporting the baiting-cloth, to keep it from bagging, together with other devices, perfecting the whole, as will be hereinafter fully set forth.l v

I employ a bolting-frame, A, having a cloth, B, the said frame moving to and fro overa box, C'.

I support the boltingframe by means of projections b b, at the lower end ofthe said frame, sliding'on plate c c, affixed to the receiver C. I 1 L i The opposite end of the frame is supported on vibrating arms D, rising from a rocking shaft, E, which -has bearings in the bottom frame or bed G'cf the machine. q

The arms D are provided with studs d, projecting laterally from the arms inward, and on which bearingplates e, having their under surface semi-cylindricel, -to fit the said studs, rest.

These bearing-plates are aixed ,to the frame A, as shown.

A Pitman, H, connects one of the arms D with the crank-pulley I, on the shaft of the speed-pulley J and ily-.wheel K, which shaft4 has bearings in the uprightsLVrising from the bed G, as shown.

Thus, by means of the vibrating arms D, bearing-plates e, projections b, and slide-plates a, I obtain a. more even amlfirm motion, which is more eicacious inbclting the stock, and less subject to wear, than is tho case when the frame is suspended by hanging rods, asin the said I. J. Gilberts patent;

The box C is supported, rin my invention, by legs Mv at one end, and by adjusting-screws g (the threads of which work in plates f, aixed to thel bed G) at the other.

The feet of the legs M restloosely in. steps inv the bed,'so that, by turning the screws g, any suitable incline can begiven to the box, asthe lower end of the latter rests on` the ends of the said screws.

By this feature of improvement, I. am enabled to conveniently change the incline' of the frame and box to suit the character of the stock being operated upon, which reqhire a greater or less incline, according to circumstances.

I also employ longitudinal ribs a` a' a, &c., preferably ot" wood, extending from end to end of the frame A, at diEerent intervals, across its bottom, and to which the halting-cloth B is axed, by tacks or otherwise.

j described, und for the several purposes set forth.

K These ribs serve .to sup-port the said cloth, and lieep it'froin' bagging down, as is the case when supported only by the frame A. I y

The cloth thus supported is cspsbleof being stretched tighter, thus keepin-g the meshes from choking or closing, which they arelisble to do when thecloth is loose -or baggy. l

h h are cross-braces, to stien the sidesotA the frnme A. v The lower end oi' the cloth is n ixed to'- a bottom crossspiece, which leaves a Vspitse, O, for the eottrser particles of 'stock to pass through and discharge into thebroad spout P, forming thelowefend of the receiver C.

Thestock, aitery passing through the boltingcloth into-the bottom of'gthe'. box, escapes-therefrom'through a spout, Q, which opens into the bottom of the receiver, near the lower end of the sa.me,t.s shown.

The bolted stock passes through this spout into e vat, to be further operatpdupou in the process of mamiy facturing starch Another feature -of improvement is the construction of the tube which conveys the ground grain and water from-the grinding-stones. It consists of 'a metal tube, made extensible by. a sleeve-joint, that is to say, byone .of the parts, S, sliding into the other part, T.

To the part T isfaiiixed a crosstube,'U, in which latter the elbow-nozzles V sro fitted.

These several parts `fit with sufficient looseness to enable'them to be turned to adjust their position; that is to say, the cross-tube may be turned on its joint, and the nozzles may be turned on their'jointsto any suit-4 able position for discharging the stock upon the halting-cloth.

The orifice of each nozzle is divided by'a septum or partition into twoorifices, as shown at n n, which are llattened to obtain a greater lateral dispersion of the watersnd stock passing through them.

The cross-tube U can be removed, to permit the removal of the frameA from the receiver 'when'the boltingl-zloth requires washing.

The machine is driven by c belt on'the speed-pulley J, which ist-composed of a number of di'erent-sized pulleys, to regulate the speed at which the separator is to be driven.

In Figure 2, u. portion of the bolting-cloth is broken away to exhibit the bottom-of the receiver, which is inclined from the sides to form e. central channel lending to the spoutQ..
